METHODS: Clinical data, including the number of remaining natural teeth, missing and decayed teeth (manifest dental caries) and root remnants, recorded by dentists according to standard practices. Medical and dental risk assessments were performed.

RESULTS: Data were available for 20,664 patients. Most were women (69.1%), with a mean age of 87.1 years (SD 7.42, range 65-109). The mean age for men was 83.5 years (SD 8.12, range 65-105). Two or more medical conditions were present in most of the population. A total of 16,210 individuals had existing teeth of whom 10,974 (67.7%) had manifest caries. The mean number of teeth with caries was 5.0 (SD 5.93) corresponding to 22.8% of existing teeth. One in four individuals were considered to have a very high risk in at least one professional dental risk assessment category.

CONCLUSIONS: Care dependent elderly in nursing homes have very poor oral health. There is a need to focus on the oral health-related quality of life for this group of frail elderly during their final period of life.
